CSF Dual-Pass Top Mount Charge Air Cooler - F8x M2 Competition, M3 & M4
The Racing & High Performance Division of CSF Inc. strives to build and engineer the most advanced, efficient, and reliable cooling systems in the world. CSF manufacturers a wide variety of sophisticated cooling systems with more than 117 different applications ranging from high performance all-aluminium direct-fit replacement radiators, to complete custom applications for race cars, power sports, off-road, marine, and industrial uses.
CSF is proud to introduce the world's first cast end tank designed top-mount intercooler for the BMW S55 engine found in the F87 M2 Competition, F80 M3 or F82/F83 M4. Utilizing multiple air dividers cast into the hot/cold side end tanks for optimized air flow, CSF designed this liquid-to-air core from a blank slate, and completed extensive testing and analysis to ensure optimum performance and cooling. The core itself is 60% larger and features a dual-core cross-flow design with 2-stage water cooling for maximum efficiency.
The CSF Dual-Pass Top Mount Charge Air Cooler is a direct replacement for BMW part number 17517846235.

One of (if not THE most) professional outfits I’ve dealt with - in the auto industry or otherwise. Needless to say, all work was carried out as promised and to an impeccable standard. Thank you Sean and team - you’ve renewed my faith in the auto business!
I have used many mechanics over the years for the many different types of vehicles in our company fleet and southern BM is one of the very few workshops I can highly recommend. Andrew and his team are also really passionate about their work and it shows.
Sean arranged a Quaife LSD for my 135i and I couldn't be happier. He advised multiple seals and bearings needed replacing unbeknownst to me so these were done as well. Now I have a more reliable car and one with tonnes more mechanical grip!
The guys are great, definitely take your BMW there.
Excellent service at reasonable prices. The shop is very nice too, you almost feel like you're at BMW.
